The biochemical functions of eukaryotic cells are often compartmentalized into membrane-bound organelles to increase their overall efficiency. Although some organelles can be formed anew, cells have evolved elaborate mechanisms to ensure the faithful inheritance of their organelles. In contrast to cells that divide by fission, the budding yeast Saccharomyces cerevisiae must actively and vectorially deliver half of its organelles to the growing bud. To achieve this, proteins called formins are strategically localized to the bud, where they assemble an array of actin cables that radiate deep into the mother cell. Class V myosin motors use these cables as tracks to transport various organelles, including peroxisomes, a portion of the vacuole and elements of the endoplasmic reticulum and Golgi complex. By contrast, mitochondria do not engage a myosin motor for their movement but instead use Arp2/3-nucleated actin polymerization for their bud-directed motility. The translocation machineries work cooperatively with molecular devices that retain organelles within both mother cell and bud to ensure an equitable division of organelles between them. While organelle inheritance requires specific proteins tailored for the inheritance of each type of organelle, it is becoming apparent that a set of fundamental rules underlies the inheritance of all organelles.
